dSIBP: a package for generating IBP seeds for QFT in de Sitter spacetime
Abstract
Recent studies show that in addition to the flat spacetime, Integration-by-parts (IBP) relations and differential equations can also provide a systematic approach to Feynman integrals in de Sitter spacetime. dSIBP is a Mathematica package for the automated construction of IBP systems and differential equations. For dS integral families with massive and massless propagators, it generates a complete set of IBP seeds, assembles linear systems for external reduction, and constructs differential equations for the reduced master integrals. The implementation combines equations of motion, remaining terms and parity constraints, and provides reliable checks. We describe the conventions and public interface through worked examples.
